As part of what is turning out to be one hell of a promotional tour around the release of his new book, Decoded, Jay-Z made an appearance on last night’s episode of The Daily Show. There’s some really good stuff here, from Jay calling for maturation in rap to saying, point blank, that a lot of rap is “shit.” You’ll also get to watch Jon Stewart go off on some totally crazy bullshit about rap being the “embodiment of Richard Pryor,” who, he says, started off doing schtick, and then “grew into an artist and began to explore himself,” even though, of course rap as a whole hasn’t gone through this process, rather just a few select rappers. But anyway.
